Minimalistic Filament Spool

I had some filament without spool and needed one that can be quickly done. Thus I decided to create a very minimalistic one myself. You just need a few M3x16-mm-screws, washers and nuts. The inner tube sits strong in the ring, if not, you can glue the two rings.

The spool is not super strong, but it doesn't need to. I Just printed it with 35% infill and 0.4 mm walls with PLA/PHA.If anything breaks I will do it again with stronger walls and more infill. But it seems it's quite good already.
